We are currently accepting data taken since January 1st 2019


These photograph positions will help verify the species identification, as every species have their own specific characteristics

Species Data Guide

After a photograph is taken, a presumed identification of the species should also be done on the field. Other information (including the presumed identification) also need to be collected if possible, including:

* Optional
Sighting Landing
Name of photographer Name of photographer

Male Elasmobranch has a visible external reproductive organ called Clasper while female does'nt (Fig 8 and 9)

TL refers to Total Length, a measurement used for shark, sawfish, guitarfish and wedgefish, which measure the length of an Elasmobranch from the snout parallel to the tip of the caudal fin. DW refers to Disc Width, a measurement for ray and skate (except sawfish, guitarfish and wedgefish), which measure the length of their body width from one pectoral fin to the other.

Identification book or guide can be downloaded from the website check Elasmo ID or you can use other identification book depending on your preferences. Information can be collected using any sort of notebook or paper, but a form can be downloaded from the project website for a prepared data collection event. Only one individual of each species sighted or landed need to be photographed from each occasion.

All photograph and data collected on the field, either sighting, landing or on board of a vessel, can then be submitted through the website. Photograph and data will then be assessed and displayed on the website. Participant of this project will be required to read and agree to the Terms and Agreements of this project, in which the general idea is to allow the flexible use of the submitted photograph and data for a variety of research and conservation purposes.


These forms can help you during data collection
